Cavaliers star guard Kyrie Irving was knocked out by an apparent shoulder injury late in the third quarter as Cleveland lost for the fourth time in five games.

Irving was hurt when he collided with Toronto rookie Jonas Valanciunas on a baseline drive with 2 minutes, 4 seconds left in the third. He shot the resulting free throws one-handed. Irving made the first, but missed the second, before walking off and heading to the locker room. He finished with 12 points.

Irving missed 11 games between Nov. 21 and Dec. 8 last year with a broken finger. He also sat out three games between Feb. 26 and March 1 with a sore right knee.
